• To ensure safety prior to commencing the repair process, allow the iPhone's battery to deplete to a level below 25% capacity.A fully charged lithium-ion battery presents a fire hazard and potential explosion risk if it sustains accidental physical damage.Deactivate the iPhone's power supply before initiating the disassembly procedure.
• The two screws, each measuring 3.5 mm in diameter and utilizing a pentalobe head, are located on the iPhone's lower edge and must be removed.
• Separating the iPhone's display assembly will irreversibly damage the integrated waterproof barriers.
• To prevent water ingress, either procure replacement waterproof seals beforehand or exercise extreme caution to avoid moisture exposure during reassembly if the original seals are not replaced.

• Excessive insertion of a prying tool poses a risk of device damage; implement the following procedure to safeguard against this by marking the tool.
• Using a measuring tool, determine a distance of3 mmfrom the tool's distal end and use a permanent marker to create a visible indicator on the prying tool.
• For enhanced precision, consider marking the remaining corners of the tool with varying measurement distances.
• As an alternative method, affix a coin to the prying tool using adhesive tape, positioning it3 mmfrom the tool's tip.

The following three actions illustrate the operation of the Anti-Clamp, a specialized tool developed to simplify the initial separation process; if this tool is unavailable, proceed to the subsequent three steps for an alternative approach.

Detailed instructions regarding the Anti-Clamp's usage are available in a separate, dedicated guide.

• To release the Anti-Clamp's gripping arms, retract the blue handle towards the rear.
• Position the arms across either the left or right side of the iPhone's frame.
• Place the suction cups close to the lower edge of the iPhone, situated directly above the home button, with one cup on the front surface and one on the rear.
• Apply pressure by compressing the cups together to establish a secure adhesive bond on the intended area.
• Should the iPhone's surface exhibit excessive slipperiness, preventing adequate adhesion by the Anti-Clamp, applying adhesive tape can enhance the grip.

• Advance the blue handle to secure the arm components in a locked position.
• Rotate the handle in a clockwise direction.Continue the rotation until a full circle, or approximately 360 degrees, has been completed.The rotation should cease when the cups begin to exhibit signs of deformation.
• Maintain proper alignment of the suction cups relative to one another; if misalignment occurs, slightly release the suction cups and readjust the arm positioning.

• Employing an iOpener, introduce it between the Anti-Clamp’s arms.Alternative heating methods, such as hair dryers, heat guns, or hot plates, are permissible; however, exercise caution to prevent damage to the display or internal battery due to excessive temperatures.Position the iOpener to rest along the iPhone’s lower edge by folding it.Allow a sixty-second interval to facilitate adhesive separation and establish a discernible opening.Introduce an opening pick into the newly formed gap.
• Should the Anti-Clamp fail to generate an adequate separation, increase localized heat and rotate the handle incrementally by ninety degrees.
• Avoid rotational adjustments exceeding ninety degrees at a time, and incorporate sixty-second pauses between each rotation.Rely on the Anti-Clamp’s pressure and the passage of time to achieve separation.The iOpener serves as a tool for initial separation.
• Heating provides the necessary softening of the adhesive.
• A one-minute pause allows for adhesive relaxation.
• The opening pick leverages the gap created.Incremental rotations of the Anti-Clamp’s handle are recommended.Excessive force can compromise the device’s integrity.
• The Anti-Clamp’s design facilitates controlled separation.Patience and controlled heat application are crucial for success.Observe the adhesive’s response to heat and mechanical force.

Instructions for detaching the display assembly utilize a suction cup, as detailed in the subsequent three procedures.

• To facilitate display separation, applying heat to the phone's lower border will reduce the viscosity of the adhesive bond.
• Employing a hairdryer or utilizing an iOpener is recommended for generating the necessary heat.The iOpener should be applied to the lower edge of the device for approximately 90 seconds to weaken the adhesive.This heating process serves to soften the adhesive securing the display, thereby easing the separation process.

Securely affix a suction cup to the bottom portion of the front panel, positioning it directly over the home button's location.

Ensure the suction cup's surface area remains clear of the home button to facilitate a complete and airtight bond between the cup and the glass.

• Maintain steady, forceful upward pressure on the suction cup to establish a minimal separation between the display assembly and the device's surrounding structure.
• Introduce an opening tool into the newly formed space.
• Due to the robust nature of the waterproof sealant securing the display, a considerable amount of force may be required to initially disengage the screen; if encountering difficulty, apply additional heat and gently oscillate the display in an upward and downward motion to reduce adhesive strength until a sufficient gap is achieved for tool insertion.

• Begin separating the display assembly from the chassis by inserting a separation tool beneath the lower edge of the phone's left side, progressing upwards towards the volume buttons and the silent switch, to sever the adhesive bond.
• Cease the separation process when the top-left corner of the display is reached.
• Avoid attempting to dislodge the display's upper edge from the rear housing, because it is secured with fragile plastic retaining clips that are susceptible to damage.

Fragile wiring is situated along the iPhone's right side; avoid inserting any tools in this area to prevent potential cable damage.

• To release the adhesive, maneuver your tool back into position at the lower-right edge of the iPhone, then slide it along the corner and upward along the right side.
• Ensure your tool does not penetrate beyond 3 mmto prevent potential damage to the delicate display cable connections.

• Employing a delicate upward motion, disengage the suction cup to elevate the lower portion of the display assembly.
• The display should not be raised beyond an angle of 15 degrees to prevent potential damage or separation of the flexible ribbon cable connectors.Maintaining the integrity of the display's internal wiring is crucial during this step.To detach the suction cup, grasp and exert force on the small protrusion located on its surface.
• This action will release the suction cup from the front panel without causing further stress.

• Initiate the iPhone's disassembly process by pivoting the screen upwards from the left edge, mirroring the action of opening a book's cover.
• Refrain from completely disconnecting the display assembly at this stage, since multiple delicate ribbon cables maintain its electrical connection to the device's main circuit board.
• Secure the display in an upright position using a support to prevent it from obstructing access to the internal components during the repair.

• Incorrect screw installation poses a risk of irreversible component damage.
• After screw removal, proceed with detaching the bracket.

• Employ the tip of a spudger to disengage the battery connector from its corresponding receptacle on the logic board.The battery connector's cable should be gently angled away from the logic board to ensure it remains disconnected and prevents unintended power delivery to the device during the repair process.This disconnection is crucial to avoid short circuits and potential damage during subsequent repair steps.
• Careful manipulation of the connector is necessary to avoid damaging the delicate components on the logic board.

• Employ the tip of a spudger to carefully disengage the lower display connector from its receptacle.For reattachment, apply pressure to one edge of the connector, ensuring it audibly clicks, and then replicate the process on the opposing edge.Avoid applying pressure to the central portion of the connector during reattachment to prevent deformation.
• Even minor misalignment during reattachment can induce bending within the connector, potentially leading to irreversible damage.

• Employ the tip of a spudger to release the connector securing the second lower display cable.Carefully separate the second lower display cable from its connection using a spudger's pointed end.A spudger should be utilized to detach the second lower display cable from its interface.

• To detach the bracket that covers the front panel sensor assembly connector, first eliminate the three screws with a 1.3 mm Phillips head.The screws, each measuring 1.3 mm in head diameter, are used to fasten the bracket to the front panel sensor assembly connector.After removing the screws, the bracket will be free from its mounting position.
• Carefully lift the bracket away from the front panel sensor assembly connector, once the securing screws have been removed.

• Detach the display unit from the device.
• If edge adhesive replacement is desired during reassembly, halt the process at this stage.

• Detach the four Y000 screws that hold the home/Touch ID sensor bracket in place.These screws, specifically the 1.2 mm screw, should be removed initially.Applying too much force while removing the screws can potentially damage the home button bracket if the 1.3 mm screws are taken out first.
  Subsequently, remove the remaining three 1.3 mm screws.After removing the screws, the bracket can then be detached.
  When reassembling the device, exercise caution to prevent over-tightening these screws.Over-tightening these fasteners could impair the functionality of the home button.The home/Touch ID sensor bracket is secured using four Y000 screws.
  A 1.2 mm screw is the initial fastener to be removed during disassembly.To avoid bending the bracket, prioritize the removal of the 1.2 mm screw before the 1.3 mm screws.
  The bracket is held in place by three 1.3 mm screws, which must be removed to proceed.
  Careful torque management is essential during reassembly to ensure proper home button operation.

• Employ a specialized opening tool to gently lift the left side of the home button cable connector, facilitating its detachment from the corresponding receptacle.Should the entire connector assembly begin to lift without complete separation, apply downward pressure to the cable's upper edge, directly above the connector, utilizing the flat end of a spudger.Simultaneously maintain upward pressure on the connector's left edge while applying the downward force on the cable.
  Exercise extreme caution during this process to prevent any damage to the cable or connector, as such harm will render the sensor inoperable.Damage to either the cable or the connector will result in permanent sensor failure.The home button cable connector must be disconnected from its socket using a prying action with an opening tool.

• Applying warmth to the region surrounding the home button and Touch ID sensor can facilitate the loosening of the adhesive securing its fragile connector, thereby simplifying its safe removal.
• Invert the display assembly and, utilizing a hairdryer or an iOpener, direct heat to the lower display edge for approximately 90 seconds to reduce the adhesive's tackiness.
• Avoid excessive heat application to the display; it should reach a temperature marginally beyond comfortable touch.

Carefully disengage the adhesive securing the home/Touch ID sensor cable to the rear surface of the display assembly, utilizing a prying tool.

• Detach the home/Touch ID sensor assembly by carefully prying it upward from the display's front surface.
• During reassembly, guide the flex cable through the designated aperture located on the display's front side, referencing the provided visual guide.
• Should your new component include additional Y000 screws positioned close to the Home Button, discard the surplus fasteners to facilitate proper reinstallation of the home button bracket.
